Yes, I understood "notes" to be those kinds of notes. I think notes are a great thing to use if they help you, but I find I don't need them. When I present, it's technical material that I know backwards-and-forwards, so I've never felt the need for notes. In particular, my slides tend to be mostly diagrams and performance graphs. I have found that when looking at and explaining figures, I can't help but remember all of the important things related to it.
